Hot melt extrusion has been a widely used process in the pharmaceutical area for three decades. In this field, it is important to optimize the formulation in order to meet specific requirements. However, the process parameters of the extruder should be as much investigated as the formulation since they have a major impact on the final product characteristics. Moreover, a design space should be defined in order to obtain the expected product within the defined limits. This gives some freedom to operate as long as the processing parameters stay within the limits of the design space. Those limits can be investigated by varying randomly the process parameters but it is recommended to use design of experiments. An examination of the literature is reported in this review to summarize the impact of the variation of the process parameters on the final product properties. Indeed, the homogeneity of the mixing, the state of the drug (crystalline or amorphous), the dissolution rate, the residence time, can be influenced by variations in the process parameters. In particular, the impact of the following process parameters: temperature, screw design, screw speed and feeding, on the final product, has been reviewed. [less ▲]

Nuclear Magnetic Resonance (NMR) is probably, with mass spectrometry, the most powerful analytical tool for the structural determination of organic compounds. For a long time and due to technical limitations, the main applications of NMR were focused on chemistry (organic, inorganic and medicinal chemistry) or biochemistry (i.e. proteins and proteins ligands analysis). Indeed, despite of very interesting potential in terms of structural information, reproducibility, specificity, quantification, NMR suffered of a lack of sensitivity and sometime of resolution in the case of complex mixture analysis in comparison with other technics. However, since several years, important technical improvements such as huge increase in sensitivity, hyphenation of NMR with LC system, automation and development of 2D and presaturation sequences have opened new putative applications for NMR, specifically in the pharmaceutical and biomedical areas. Then, beside the mass and chromatographic technics classically used for drug analysis, NMR represents an interesting and complementary tool for many applications. In this presentation, we will describe some NMR applications related to the pharma area. Starting from the identification of xenobiotic metabolites by coupling LC-SPE-NMR data with LC-MS/MS results, quantification of cyclodextrines in complex media, identification of illicit compounds, we will finish with our recent metabolomics NMR developments.
